I'd like to be able to find any possession item at home without looking for it in miscellaneous boxes I keep them in. I also would like to move separate items of my stuff from one box to another and keep being able to spot them after they've been moved. The solution that seems to me optimal is to create a folder for every box and to create subfolders for each plastic container within the box. The subfolders should consist of spreadsheets. A separate spreadsheet for each item. That is, I should create a separate spreadsheet for my summer jacket I'm unable to find right now. As well as a separate spreadsheet for my distant relative's spare apartment door key he gave me to keep in case he looses his own one. If you have another solution, can you offer one? It should be free. It's OK if it's MySQL, for example.
